I am trying to recommend to my users to change IE to Firefox at work, but every time i open a site i get this "Authentication required" message box, which is bothersome.. i put the username and password but in a few minutes i get the message again (this doesn't happen with IE or Chrome, only Firefox). How can i remove this "authentication required" message box to tell my users to change for a better navigator get more power ? i really want to change their experience through the web. I hope you can help me. Thanks
